Cliff Alexander suffered a sprained ankle in a KU workout last week and is currently in a walking boot. In a text message to the Lawrence-Journal World, Self said Alexander will be “immobilized” for a “few weeks.”

Alexander’s injury was discovered after Frank Mason posted a picture on Instagram. Alexander is seen (on the left in the picture below) in a walking boot.

Cliff Alexander, who is ranked in the top by all recruiting services, is an incoming freshman at Kansas and is expected to fill Joel Embiid’s hole in the starting lineup.

Alexander averaged 24 points, 15 rebounds and six blocked shots per game in his senior season at Chicago Curie High.

Alexander participated in the McDonald’s All American game this year in Chicago. Two days prior to the game, Alexander injured his hand in the Powerade Slam Dunk Contest. Despite the injury, he still played in the all star game.
